Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-15252 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.xwiki.platform:xwiki-platform-oldcore (Maven): affected all versions; fixed in 11.10.6\n- org.xwiki.platform:xwiki-platform-oldcore (Maven): affected all versions; fixed in 11.10.6\n- org.xwiki.platform:xwiki-platform-oldcore (Maven): affected from 12.0; fixed in 12.5\n- org.xwiki.platform:xwiki-platform-oldcore (Maven): affected from 12.0; fixed in 12.5\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2020-15252/ (Markdown: https://insights.sbomify.com/CVE-2020-15252/index.md)","id":"CVE-2020-15252","markdown":"https://insights.sbomify.com/CVE-2020-15252/index.md","name":"CVE-2020-15252","record":{"aliases":["GHSA-5hv6-mh8q-q9v8"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"XWiki platform","requires_auth":"low_privilege","summary":"Users with script rights can execute arbitrary code by accessing the Servlet context to instantiate Java objects.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"xwiki","vendor":"xwiki"}],"cvss":{"score":8.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-74","name":"Improper Neutralization of Special Elements in Output Used by a Downstream Component"},{"id":"CWE-94","name":"Improper Control of Generation of Code"}],"description":"In XWiki before version 12.5 and 11.10.6, any user with SCRIPT right (EDIT right before XWiki 7.4) can gain access to the application server Servlet context which contains tools allowing to instantiate arbitrary Java objects and invoke methods that may lead to arbitrary code execution.
